To all whom, it may concern 5 Be it known that I*.JOIIN-iL., Bi-\RNE S, a. citizen of the United States; residing at. Lexington. in the county of-eFayette and- State of Kentucky. have invented certain; new and useful? Improvements in, klemp- Breakers, of which therfollowingis a speci fication.

This invention relatesto improvements in machines for breaking hemp and: similar fibrous-material and has: for its primary.

object to provide a machine of this character in which the stalks-to. be:broke1iarewfed into the machine side-wiseandare -inter-.

mittently acted upon' at various points. throughout their length during- -'theirpassage through the machine. by series of'mov- J: P machine-upon the inclined brace rods 8."-' Another ob ectis the provision-of'amwa ing breaker bars.

chine of this character includingsuperposed banks of breakers.- each bank consisting of a series of units and an actuatingmocha: nism capable ofvaryinghthe movement of the respective units so as to intermittently act upon the stalks at -various points throughout their length.

1V ith these and other objects in view as.-

will appear as the description proceeds the invention comprises the novelfeatures of construction, accompanied by elements and arrangement of parts whichwill be more fully described in the following specification and set forth with particularity, in the 1 ims appended hereto. 7

Referring to the drawing in detail, where- If f KEMP-B EAKER; .1. r' r v a tei rsratent- Patented July 29', yApplication ragaA ara-miscseriarneesasw;"

opposite sides of the frame structure and" the-beam at the dischargeside 'Of'tl'lfifnlfi-.

bars, which will behereinaftermore fully described,v are supported at an inclinatioirpermitting the stalksto slide by gravity along the bars and finally off into a suitable receptacle;

and the main drive shaft is connected by a belt- 13 with a-cain shaft 1. 1 ibtatably sup ported adjacent the receiving side of the A series of breakerbars-1Z .-.is arranged Annaindrive shaft 11 is supported in bearings secured at the-top of the frame for sliding movement upon the supportingbeams 10 and the bars-are arranged f in groups,-. of approximately. 65 bars .to the; group-and the bars of each 'group are con--v nected by strips 16 whereby they are rigidly comiected and formed into'aunit capable;

of reciprocation upon the supporting beams 10. The connectingstripof each group of breaker bars is provided with a bracket 17 having pivotal connection with a belt;

18. engaging-a cam or eccentric .19 ofthe shaft; 1 1 whereby reciprocatory movement: 15 transmitted tothe group ofbars during;

the rotary movement of the shaft 1 1 and the cams are arranged in various angular relations upon theshaft 14 so that the movement of the respective bar groups, varies:

according to-the arrangement'of the cams upon the shaftf The longitudinal members 9 are connected at uniformly spaced intervals between-the transverse members 8 by cross bars20 and bearings 21 are supported upon the bars wherebythe latter are utilized assupple-'- mentary means for supporting the shaft 11.

25 are arranged above the lower groups and the bars of the respecti v groups 25 are connected by strips 26 to iiclf'are' at tached upright bearing members 27 l vi ng. looped upper terminals connected wit1 the crankpinof the cranks 23 and 24. As shown in" 1 a, treatises" 26' are asaagar adjacent the opposite endsrof the bars 25. and the upper breaker bars are arranged in staggered relation to thelower bars in order that the upper bars may. enter between the lower bars and more effectively separate the 'fihers ofthe hemp or other materiah structure 5 at relatively high terminals of the breaker bars and the lower feed roller is constantly driven during the. operation of the machiiie to feed stalks of hemp or other fibrous material between the shanks of breakers by a drive chaih 32 extending between the main drive shaft 11 and the extended terminal-of the shaft of the lower feed roller. The material to be operated upon is introduced sidewise between the rollers, that is with the axes of the stalks disposed parallel with the axes of. the rollers;

In the practical operation of the machine the lower groups of breaker bars 15 are variably movedby the connections 18 with the cams l9, the'movemen't of the shaft 11 being transmitted to the .canr :shaft 14 through the drive chain 13 the rotary inove ment' 'of the 'pinsofthe cranks 23 and 24 is transmitted to the upper groups of-bars; 25 through the hearings or pitman rods 2? imparting a variable vertical reciprocatory movement, to the upper groups which coact with the lower bars to effectively separate the fibers of the material lying between the bars:

What-l'claimis z 1 1. A hemp breaker including a frame;

structure, superposed series of bars movside and in groups, means connecting the bars of each group, crank shafts supported in the upper portion of the fran e means connecting the crank pins of the shaft-with "-theiz'igroups :of the'gupper series whereby movement is transmitted thereto, and means for aetuatmc the bars-of the lower grou as. 2; -'A' lie111p breaker including a frame structure;lsuperposed series of hars supported in the frame-structure by means for actuating the bars of the upper series, a cam shaft journaled in the lower portion of the frame structure vprovided with a series of cams and means connecting the cams with the bars of the lower series to actuate the latter.

3; hemp breaker ihcluding a frame structure, superposed series of bars supported in the frame structure,- a crank shaft journaled in the frame structure, means connecting the crank pins of the shaft with the bars-of the ripper series; whereby movement is transmitted thereto during rotary movement of theshafts, a cam shaft journaled in the lower portion of the frame structure and provided with a series of cams,- and means connecting the'cams with the' bars of the lower series whereby movement is transmitted thereto.

4. A hemp breaker including a frame structure, superposed series of breaker bars supported in the frame structure, the bars of each series being arranged in groups,- means connecting the b'ars of each grdup,a crank shaft journaled in the frame structure provided with a series of variously dispbsed crankpins, means connecting the several crankpins with the respective groups of bars of the upper series, a cam shaft j our nal'e'd in the lower portion of the frame structure and provided with a series of va riohsly disposede'ams, and means connecting the cams with the respective groups of the loiver series whereby movement is transmittedthreto. t.
